# selfupdate: Build self-updating Go programs
> NOTE: Original work at github.com/inconshreveable/go-update, modified for the needs within MinIO project
Package update provides functionality to implement secure, self-updating Go programs (or other single-file targets)
A program can update itself by replacing its executable file with a new version.
It provides the flexibility to implement different updating user experiences
like auto-updating, or manual user-initiated updates. It also boasts
advanced features like binary patching and code signing verification.
Example of updating from a URL:
```go
import (
"fmt"
"net/http"
"github.com/minio/selfupdate"
)
func doUpdate(url string) error {
resp, err := http.Get(url)
if err != nil {
return err
}
defer resp.Body.Close()
err := selfupdate.Apply(resp.Body, update.Options{})
if err != nil {
// error handling
}
return err
}
```
## Features
- Cross platform support (Windows too!)
- Binary patch application
- Checksum verification
- Code signing verification
- Support for updating arbitrary files
